obama? some final thoughts from our round table right after this. [ j. weissman ] it was 1975. my professor at berkeley asked me if i wanted to change the world. i said "sure." "well, let's grow some algae." and that's what started it. exxonmobil and synthetic genomics have built a new facility to identify the most productive strains of algae. algae are amazing little critters. they secrete oil, which we could turn into biofuels. they also absorb co2. we're hoping to supplement the fuels that we use in our vehicles, and to do this at a large enough scale to someday help meet the world's energy demands.
